Sennheiser CX 275 S Universal Mobile Headset

These are amazing headphones for any basshead who desires a nice clean sound. Though the balance is a little bit wonky, the clarity is all registers is amazing. The sound isolation is decent. I use these in school hallways and can't hear anything or anyone if the volume is at 50%. The bass is super powerful but to the point that it makes the mids and treble pale.
